>>14398257Honestly this image is one of the best descriptors in a school textbook ever made. Even as a 3rd or 4th grader, I was able to easily learn geographic terms that have stuck with me for my entire life. It's so iconic that this obscure image can be posted and people will actually recognize it, in spite of not trying to be flashy at all. A few things remain unclear, like a Sound v. Bay or a Plateau v. Mesa, but you can use context clues to figure it out and those are questions that would probably exist in almost any diagram.
In any case, it's literally perfect. You could hardly make a better graphic if you tried.
